ABSTRACT:
An improved image producing apparatus relating to the display of images including text, line graphics, continuous tone photographs, and halftone pictorials is disclosed. The apparatus includes, for example, a CCD scanner for scanning a scene for producing a data image of a scene for a processor. The processor includes means for transforming the data image to a set of assigned density values according to a look-up set of assigned density values stored therein, means for partitioning a page of image data into adjoining blocks of pixels such that each individual block can be further partitioned into smaller sized sub-blocks until the smallest sub-block is reached, which is one pixel; micro-structure control means for adding a screen function to the transformed image data or introducing cumulative row error sums for influencing the order of dot placement and not to alter the averaged image density for each block of pixels; and means for recursively processing the data for error minimization in successive steps of refinement with each additional step improving the image data approximation of the previous step until the print error sum of each block is minimized. A decoder then decodes the image data block for printing by a printer.
